Enhanced version of VNC, called TightVNC (grown from the VNC Tight Encoder
project), which is optimized to work over slow network connections such as
low-speed modem links. While original VNC may be very slow when your
connection is not fast enough, with TightVNC you can work remotely almost
in real time in most environments. Besides bandwidth optimizations,TightVNC
also includes many other improvements, optimizations and bugfixes over VNC.
Note that TightVNC is free, cross-platform and compatible with the standard
VNC.

Make fonts repecting XDG
Xorg is now looking in ${LOCALBASE}/share/fonts by default
Xorg now accepts symlinks in etc/X11/fontpath.d (as decribed in Xserver(1))
Large cleanup on lots of font ports
All fonts are now properly dynamically generating fonts.dir and fonts.scale
instead of sometime overwriting existing ones)
All fonts are generating fontconfig's cache
Improve consistency in fonts ports

New USES imake to handle the dependency on imake.
This uses accept 'env' as an argument for ports that do use their own or a
different do-configure target.
Modify xmkmf so it accept IMAKECPPFLAGS as default flags for imake and pass it
to the called imake.
Modify xorg-cf-files (the FreeBSD.cf configuration file) to allow CppCmd to be
overwritten.
Pass CppCmd CcCmd and CplusplusCmd via command line to each call of imake via
IMAKECPPFLAGS
Pass IMAKE_DEFINE with the above arguments to MAKE_ARGS so that imake spawned
from Makefile generated by a previous
imake also inherit the defined CppCmd CcCmd and CplusplusCmd.
Make imake use devel/tradcpp all the time, so that when buidling with clang we
do not depend on gcc's cpp.
Make imake respect CC and CXX
Make imake respect USE_GCC (if set imake will use gcc's cpp).
While here:
- Remove a couple of indefinite articles from comments
- Trim headers
- Fix a couple of ports to build with clang or use: USE_GCC=any
- Fix a now useless redefinition of the extraction chain
- Fix a typo in japanese/Wnn7-lib bundled imake template definitions
- Fix some XMKMF execution with no env specified
- Use options helper in x11/xautolock to simplify the port

- Update X.org ports to 7.4+ (few ports are more recent than the katamari).
- Bump PORTREVISION for all ports depending on libglut since the shlib
version number went from 4 to 3.
- Bump PORTREVISION for all ports depending on libXaw as libXaw.so.8 isn't
installed anymore.
- Couple of ports fixes (mostly missing xorg components added to USE_XORG).

- Add the X_WINDOW_SYSTEM={xorg,xfree86-4,xfree86-3} variable to bsd.port.mk,
and make XFREE86_VERSION map to it. XFREE86_VERSION is now deprecated.
- Make xorg the default X_WINDOW_SYSTEM on -current.
- Add several new X_*_PORT variables which point to various pieces of X11 based
on the setting of X_WINDOW_SYSTEM, and make ports use them.
- Add information to CHANGES about how to handle the transition.

When checking if net/vnc is already installed, check for a port-specific file.
bin/Xvnc is shared, so the IGNORE setting would also be triggered when
tightvnc itself is installed (stopping portupgrade from doing upgrades).
